Aviation Glossary

**Term:** EASA Form 1

**Category:** Airworthiness & Maintenance

## How It Is Used

It documents approved release status but does not by itself prove that a part is suitable for installation on every aircraft; eligibility and configuration still need to be checked.

## Where It Sits in Continuing Airworthiness

EASA Form 1 forms part of the technical framework used to establish, maintain or document aircraft airworthiness. Applicability depends on aircraft type, authority, approved maintenance data and the operator's maintenance programme.

## Records and Transaction Impact

Technical status must be supported by current records. Buyers, lessors, lenders and MRO organizations normally verify the applicable document, revision, compliance status and remaining maintenance exposure rather than relying on a description alone.
